The Metro Gold Line Foothill Extension Construction Authority (Construction Authority) is an independent transportation planning, design and construction agency created in 1998 by the California State Legislature, SB 1847 (later updated in 2011-AB706 and 2012-AB1600). The agency was created to immediately resume design, contracting and construction of the Los Angeles to Pasadena Metro Gold Line (formerly the Pasadena Blue Line) which had been suspended by the Los Angeles County Metropolitan Transportation Authority (Metro) earlier that same year.

The newly formed Construction Authority completed the Los Angeles to Pasadena segment in just under three years, and the 13.7-mile line opened in 2003 on time and under budget.

The same legislation that created the Construction Authority also dictated its role to plan and construct any “fixed mass transit guide way eastward to Claremont.” The planning for the line was later extended to terminate at Montclair’s Transcenter, a regional transit hub for numerous bus and rail operations serving San Bernardino County and the Inland Empire.

Once construction is complete, the Construction Authority transfers the project to Metro to operate. This relationship is formalized in a Master Cooperative Agreement approved by both agencies’ boards of directors. The current Master Cooperative Agreement, signed in July 2010, manages the relationship for planning and construction of the next two segments of the Foothill Extension from Pasadena to Azusa and Azusa to Montclair.

Project Funding

The Los Angeles to Pasadena segment was funded through Propositions A and C (state and local funding). These funds were already in place when the Construction Authority was established and took over construction of the project in 1998.

The Foothill Extension segments (Pasadena to Azusa & Azusa to Montclair) are estimated to cost $1.6 billion (not including a final extension to LA/Ontario International Airport). The majority of the funding is coming from Los Angeles County's Measure R, which went into effect in July 2009.

In 2010, the boards of directors for the Construction Authority and Metro approved the Funding and Master Cooperative Agreements between the two agencies. This was a significant milestone for the project – laying out the framework and mechanisms for $810 million to be allocated to the project between 2010 and 2019, and also formalizing the roles and responsibilities of both agencies during design and construction of the project.

The majority of the $810 million will be used to design, build and purchase equipment to operate the Foothill Extension from Pasadena to Azusa and complete planning for the segment from Azusa to Montclair. A significant gap of additional funding will need to be identified to construct the Azusa to Montclair segment. The Ontario Airport Extension is currently unfunded.

The Construction Authority is governed by an eight-member Board of Directors. In addition, cities from South Pasadena to Ontario are represented on two additional boards to the Construction Authority--the Joint Powers Authority (comprised of elected official representatives appointed by each corridor city) and Technical Advisory Committee (comprised of city managers or their staff appointees).
